Relational vocabulary: in a relation, are columns sometimes called “attributes” (the formal term in the relational model)?

Introduction / Context:
Terminology matters in data modeling. The relational model uses the term “attribute” to refer to what many SQL tools and users call a “column.” This question checks recognition of the formal term.

Given Data / Assumptions:

• We are discussing the relational model, not specific vendor terminology.
• “Attribute” is the formal name; “column” is the common name.
• The statement says “sometimes called ‘attributes’,” acknowledging both usages.

Concept / Approach:
In the relational model: table → relation, row → tuple, column → attribute. Using “attribute” emphasizes that each column draws values from a defined domain (type) and participates in constraints such as keys and dependencies.

Step-by-Step Solution:

Verification / Alternative check:
Review any normalization discussion; you will consistently see “attribute” used.

Why Other Options Are Wrong:

• “Incorrect” conflicts with the widely accepted terminology.
• Mentions of other models or key membership are irrelevant to naming.

Common Pitfalls:
Thinking that “attribute” and “column” have different meanings; in relational theory they correspond.

Final Answer:
Correct
